Pitch your idea/new feature to add
Allow backing up states of a workspace in a manual basis at any point of time so that the users have the liberty to fall back to the snapshot of their choice, should things not go the way as they were planned. This should be stored in the SWD file as well so one file can have multiple versions of the same document and it would be left to the user as to decide which one to open up and use.
